Gets the next link in the list, or NULL if there are no more links. Used for iteration.
DBusList *link; link = _dbus_list_get_first_link (&list); while (link != NULL) { printf ("value is %p\n", link->data); link = _dbus_list_get_next_link (&link); }

Allocates a linked list node. Useful for preallocating nodes and using _dbus_list_append_link() to avoid allocations.

|
Appends a value to the list. May return FALSE if insufficient memory exists to add a list link. This is a constant-time operation.

|
Appends a link to the list. Cannot fail due to out of memory. This is a constant-time operation.

|
Frees all links in the list and sets the list head to NULL. Does not free the data in each link, for obvious reasons. This is a linear-time operation.

|
Copies a list. This is a linear-time operation. If there isn't enough memory to copy the entire list, the destination list will be set to NULL.

|
Finds a value in the list. Returns the last link with value equal to the given data pointer. This is a linear-time operation. Returns NULL if no value found that matches.

|
Calls the given function for each element in the list. The function is passed the list element as its first argument, and the given data as its second argument.
